Parrotic

[Little_Girl]

The process of repeating information or behavior with minimal or zero comprehension of the subject matter (much like [the parrot] bird repeats human speech).
[Parrotic] information or behavior results in a cascade effect influencing the percentage of humans that find the information or act reasonable enough to parrotically [propagate] to others.
Even a small [parrotic] event can lead to death. Example: law enforcement takes lethal action based on parrotic information.
Large scale parrotic events can and have lead to war. But, in that context is more commonly defined as : propaganda.
